This invention relates to a meth'od o'i treat ing elastic webbing to preclude recession ofl Another object is to provide a novel means of securely anchoring the elastic elements 15.2 along a severed edge of elastic webbing.

Another object is to provide a flexible binding for an edge of elastic webbing These and other objects are attained by the means described herein and disclosed in the so .2 accompanying drawing, in which:

Fig. 1 is a top plan view of a stripof webbing having interwoven with the fabric thereof a series of longitudinal elastic elements.

Fig. 2 is a side elevational-view showing the method of treating the strip.

Fig. 3 is a perspective view showing the effect upon the elastics produced by the treating of the strip of webbing.

Fig. 4 is a view similar to Fig. 2 showing how the treating operation may be performed while the elastic webbing isin stretched'or partly stretched condition.

Fig. 5 is a plan view showing how elastic 5Lwebbing, treatedin accordance with the invention, may be joined to provide a serviceable, single thickness joint.

In the manufacture of elastic webbing which consists of interwoven fibres and elastic 4oielements, usually of rubber, the elastic ele:

ments either are deliberately stretched during the weaving operation in order to insure a tight weave when stretched and elongated by reason of the lateral pressure exerted 45 thereon by the weaving which'envelopes them. In Fig. 1 is disclosed a strip of elastic webbing comprising the interwoven fabric body 6 and the longitudinal spaced parallel elastic elements 7 When such a strip of elastic web- 50 bing is cut from a continuous-reel or roll and subsequently used in' a stretchable arti ole; theelastic elements invariably recede-into} the webbing unless they are 'firnrly anchored atithe severed :enc ls'r Thense ofg stitehi-n g antl adhesive tape for anchoring said ends has mtfiucproven entirely; satisfactory "because-of the damaging. effect of thesewing nee d le ort-the? elasticsyanrl the liability-of the stitching and tape to loosens 'l he .foregoing di sadvantag es are obvl'atetl" 06 by: applying to the webbing fi, trariswn-s'ely; thereot; a -lnarrowi coating 9 0i fluid cement} suelr as :rubber cemenfi and then placing them:- oniazst'rip 10 oat-uncured'rubbegthestrip and webbingbeingthen pl aced between thelieatd l 66 elementsiillfland '12 ot a I vulcanizing which :vulcan izes the-uncured rubber to each? o'fl; the elastic element's; through the' fab'r'iei The el astic elements are thereby j oin'edf as' indieated d iag rammatieally iri Figif3}- WitH-Wb the-elastic elements thus-joinedi and-secured! also toat-he fabrie of the webbing, a-cut ma'ybe made cen tral ly' 0t the vulcanized 'portiom 13, as indicatedby broken line -14, unattend- 7 ed: flbyi'recession of the elasticelements into 78 thefabric witkr the-undesirable results abtwe mentioned.

An indicated in F-igi4, the"-elastfo'webbing" may be stretched during the application of the cement and uncured rubber strip, and held so during the vulcanizing operation by any suitable means such as clamps 18. This facilitates entry of the cement and rubber between the fibres of the webbing during the treatment. Asindicated at 8, (Fig. 1) the vulcanizing process may be applied to the I edge of the webbing subsequent to the cutting plied for holding the edges in abutting relationship. Thisconstruction provides asingle thickness connection which would cause no discomfort to a wearer when applied to bandages, supports or wearing apparel. De-

-velopments in the art of scientifically designed elastic bandages, arch braces and the likedemand that the elasticity of the webbing be preserved so that each elastic element may share in scientifically supporting affected .:parts of the injured or affected portion of the human body. When such bandages and supports are stitched or sewed to retain the elastic elements in position, one or more of the elastic elements invariably are broken, weakrened, or lost in the sewing operation. The

present invention provides a means wherebyv the elastic elements are kept under control for perfectly supporting the affected parts;

What is claimed is:

1. .The method of cutting to preclude recession'ofthe elastic elements inelastic webbing comprising appl ing to the elastic webbing along the line 0 cutting a fluid cement adapted topenetratethe fibres of the webbing and tocontact the elastic elements, ap-

plying to the cement a strip of uncured rubber, vulcanizing the cement and uncured rubbing comprising stretching the elastic webbing, applying to the elastic webbing along the line of cutting a substance for binding the elastic elements to one another while the elastic webbing is stretched, then cutting through the substance along the line of cuttin f The method of anchoring the elastic elements of elastic webbing, comprising applying a vulcanizable substance to the surface of the webbing while stretched and then vuleanizingsaid substance to the elastic elements through the webbing.

5. The method of anchoring in a predetermined area the elastic elements of elastic webbing, comprising applying a binding'substance to the surface of the webbing in said area while the webbing is in a stretched condition. v
